Reactjs 为UI kitten Select设置唯一的选择

我有一个列表，我在React native UI Kitten中循环生成一个选择元素列表。在该循环中，我为每个选择项都有一个循环，选择一个激活其他项如何使选择对每个选择元素唯一

这是我的密码

export default function SelectSubjects() {
const [selectedIndex, setSelectedIndex] = React.useState(new IndexPath(0));
return (
        {        
       
        getSchoolsubjects().map((subject, key)=>(

         <Card style={{height:wp('15%'),marginTop:20}}  key={key} >  

            <View >
              <CheckBox style={{alignSelf:'flex-start'}} checked={checkSubjects(testSubjects,subject)} 
              onChange={()=>setSubjects(subject)} >
                     {subject}         
              </CheckBox> 
            </View>  

            <View>
             <Select style={{alignSelf:'flex-end',marginTop:-wp('8%')}}
                selectedIndex={selectedIndex}
                onSelect={index => setSelectedIndex(index)}
                placeholder='Select year'
                
                >

                {getSchoolSchoolYears(subject).map((year:number, index:number)=>(
                    <SelectItem    key={index} title={year}/>
                )) }   
                
              </Select>
            </View>               
                

                      
         </Card>

          ))}

)

<View>

</View>

}

导出默认函数SelectSubjects（）{
const[selectedIndex，setSelectedIndex]=React.useState（新索引XPath（0））；
返回(
{        
getSchoolsubjects（）.map（（主题，键）=>(
设置主题（主题）}>
{主题}
setSelectedIndex（索引）}
占位符=“选择年份”
>
{GetSchoolYears（主题）.map（（年份：编号，索引：编号）=>(
)) }   
))}
)
}
